Rewritten from Sogou WeChat rc.8 coverage themes plus the public GitHub release notes. Not a verbatim WeChat reprint.

What installers should notice
rc.8 is the first big public-beta bump after launch week: multimodal inputs, richer subagents, Windows terminal polish, and a pile of gateway/streaming fixes. For a hub view that also tracks catalog gaps, see our rc.8 landing.
Images in the loop
DeepSeek adapters can enable native image requests. /goal and /plan accept image context; the @ menu can pull files and sessions into the task. That does not mean every hosted model path is vision-ready — read vision notes and prefer verified packs when the narrative outruns the API.
Tool-layer “sight” still exists
If the model is text-only, OCR / pixel-stat style tools can still approximate screenshots. Treat that as evidence assembly, not photo understanding. Community packs such as modlens and dsh-vision-toolkit live in that lane.
Claude Code & Codex as bundles
Both can install as Profile Bundles. Codex supports non-interactive permissions and named instances. Details: subagent guide.
Windows PTY
Persistent PowerShell sessions land in the PTY path and are on by default in Minimal — fewer “terminal forgot my env” moments.
Fixes worth knowing
- Large or many images less likely to blow the request
- Streaming cancel keeps usable prefixes for the next turn / fork
- Custom OpenAI-compatible gateways get fewer format/reasoning gaps
dshbase habit
Upgrade the harness, then verify plugins again. Marketing posts move faster than directory checks — use audit before you trust a random vision bridge.
